HARRY B. HAIGH, OF BROOKLYN, ASSIGN OR TO THE IRON GLAD MANU FACTURINGCOMPANY, OF NEW YORK, Y.

ELEVATOR-BUCKET.

EPECIPICATION forming part of Letters Patent No. 336,916, dated March 2,1886. Application filed June 27,1885. Serial No. 169,946. (No model.)

To all whom it may concern.-

Be it known that I, HARRY B. HAIGH, a citizen of the United States.residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Elevator-Buckets, ofwhich the following is a full, clear, and exact description. 1

This invention relates to certain improvements in. elevator buckets,particularly designed for buckets of spherical shape, like thosedescribed in Letters-Patent Nos. 148,429 and 180,329.

The object of my invention is to increase the strength and durability ofthe bucket where it is subjected to the greatest strain in use withoutincreasing the cost of manufac,

ture to any appreciable extent.

In the accompanying drawings, in which similar letters of referencedesignate like parts, Figure 1 is a perspective view showing the flangebefore it is bent over. Fig. 2 is a side view showing the two rows ofrivets, and Fig. 3 a top plan view. Fig. 4 is a central vertical sectionof the finished bucket.

a designates the front of the bucket, which, as shown, is a'segment of asphere.

b designates the back, having a forwardlyprojecting flange, 0, extendingfrom its upper edge down around its bottom and up again to its upperedge on the opposite side, the width of the flange increasing graduallyfrom its lower edge, 02, to its upper edge, 6. This flange c is slit ateach side at the point marked 3 5 f, and the surplus metal at the upperedge, h,

is bent and lapped over the back, and the projecting ends 9 g are bentand lapped over described.

the flange 0, thus making two thicknesses of metal where the bucket isto be secured to the belt, and three thicknesses at the corners, wherethe strain on the bucket in use is greatest. The front of the bucket isriveted t0 the flange c and ends 99, a single row of rivets being usedalong the narrow portion of the flange, and a double row at the wideportions and the three thicknesses of metal at the corners.

Aloucket of this construction will be strong and durable and welladapted to stand the strains incident to its use.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. An elevator-bucket having its back provided'with aforwardly-projecting flange of gradually-increasing width, extendingfrom edge to edge, combined with the front, secured to said flange byrivets,
